LDA-F Liquid Detonation Flame Arrester

Brand: PROTEGO
Request Information
The Protego LDA-F series of liquid detonation arresters was developed for storage tanks filling and drain lines that are not continuously filled with product and sometimes contain a combustible mixture. 

The integrated siphon protection with Protego flame arrester unit additionally prevents the liquid in which the lines are immersed from being siphoned off while the container is being drained. 

The Protego flame arrester consists of several FLAMEFILTER discs and spacers firmly held in a FLAMEFILTER cage.
Features
  • Siphon protection offers a high degree of safety
  • Minimum risk of soiling
  • Low pressure loss
  • Provides protection from deflagrations and stable detonations
  • Useful for nearly all flammable liquids
  • Meets TRbF (Technical Regulations for Flammable Liquids) requirements
  • Deliverable with different outlets
